Soil erosion is the process by which soil is removed from one location and deposited elsewhere. This can occur due to various factors, including water, wind, and human activities. There are three main types of soil erosion: water erosion, wind erosion, and human erosion.
Water erosion: Water erosion occurs when water, either from rainfall or irrigation, removes soil from one location and transports it to another. This can occur due to the force of the water itself, or through the action of flowing water carrying soil particles with it. Water erosion is a common problem in areas with heavy rainfall or poor drainage, as well as in areas where soil has been compacted or lacks vegetation.
Wind erosion: Wind erosion occurs when wind removes soil particles from the surface of the ground and carries them away. This is more common in dry, arid areas where there is little vegetation to anchor the soil in place. Wind erosion can also be caused by human activities such as farming, construction, and land development, which can disturb the soil and expose it to wind erosion.
Human erosion: Human erosion occurs when human activities, such as farming, construction, and land development, remove soil from one location and deposit it elsewhere. This can occur through activities such as plowing, grading, and bulldozing, which can disturb the soil and expose it to erosion. Human erosion can also occur through the use of heavy machinery, which can compact the soil and make it more prone to erosion.
Preventing soil erosion is important for maintaining the productivity of soil and the health of ecosystems. Some strategies for preventing soil erosion include planting vegetation, installing erosion control structures such as terraces and retaining walls, and practicing sustainable land management practices. By understanding the different types of soil erosion and taking steps to prevent them, we can help protect our valuable soil resources for future generations.
Soil Erosion Basics, Types And Causes
These particles can rise by 60cm above the soil surface. When it is just starting out, the erosion is mostly vertical in nature, which is why valleys usually have a V-shape. On the other hand, abrasion occurs when the surface of the soil is worn down when it is struck by airborne particles carried by the wind. Trees, hedgerows, and other plants cultivated as wind blocks can also be helpful. Erosion increases the amount of dust carried by wind, which not only acts as an abrasive and air pollutant but also carries about 20 human infectious disease organisms, including anthrax and tuberculosis. On a rolling or steep landscape, water penetrates through a vulnerable soil crack or hole, such as a rabbit burrow, or where an old root has decayed, and soil disperses and is carried away within the flow to form a wide underground channel or small tunnel.

They fall into three broad classifications ranging across small clay , medium silt , and large sand. Implementing rotational grazing and other mindful practices can limit soil compaction and erosion. It can lead to a decline in crop yields, loss of topsoil, and increased runoff of pollutants. Large offshore wind turbines can alter the flow of water downstream and contribute to bank erosion. Secondly, tunnel erosion is enhanced by the presence of weak subsurface soil zones. The most widespread landforms of erosional coasts are sea cliffs.
Prolonged occurrence of soil erosion through inter-rills, leads to widening of inter-rills and formation of small channels. Soils with low clay content are less cohesive and are inherently more unstable. Specifically, it is an example of streambank erosion. Causes of Soil Erosion Securing a continuous surface cover of the soil, such as trees, pasture, or meadow, is the most efficient technique to reduce erosion. .
Eventually, the narrow strips of land separating the multitude of rills will be swept away, leaving one larger scar behind. This can result in a few square meters being made infertile. The whole process begins to speed up when the inner layer gets even more exposed to the free flow of water. This can result in evaporation, desertification, increase in airborne dust, crop damage, and land degradation. Coarse sand and gravelly or rocky soils are also more resistant, since the particles are too heavy to be removed by wind erosion. Wind erosion is common on flat, bare areas with dry, sandy soils, or anywhere the soil is loose, dry, and finely granulated. Aside flooding, any human activity that causes a significant shift in the flow pattern of streams and rivers can lead to bank erosion.
Gullies are formed when there is more continuous erosion from rills and also due to the subsurface soil erosion. Soil conservation is the technique of preventing soil erosion. Specifically, it is an example of streambank erosion. Soil deterioration and low water quality due to erosion and surface runoff have become severe problems worldwide. The best preventative measure against sheet erosion is a robust vegetative cover. Accessed 28 August 2022.
In order to prevent excessive erosion, we must first seek to understand the different types of soil erosion. What are the soil erosion? But it is harmful since it removes the finer and more fertile topsoil. This typically represents the first stage in soil erosion. These banks begin to migrate slowly along the coast, creating a long-shore drift. A good example is the Grand Canyon, which was formed by the Colorado River. They mostly occur across fracture zones that have already been weakened.
Soil erosion is an ongoing battle between various forces. This is why it is important to study all the different types of soil erosion carefully so that we can work together to combat the adverse effects of our human activity. Glacial erosion can sculpt down complete mountains and carry huge pieces of land along with them. Mass Movement A mass movement can cause erosion due to the movement of rocks or sediment against a sloped surface. What are the examples of water erosion? It is also likely to occur when stormwater is concentrated within small, defined areas, and flows outward in a radial pattern.
However, wind and water are the biggest contributors to removing even more soil. The soil can harden and seal off due to the mixture of small amounts of clay with large amounts of fine sandy soils. Grazing can also significantly increase the chance of wind erosion. Loss of topsoil is a major risk, as is the reduction of crop production potential in the area. Scalding Erosion as one of the types of Soil Erosion Scalding erosion is a type of erosion whereby wind or water, forcibly removes the topsoil and exposes subsoil to degradation.
